minutes.

7 Minutes Time Save Control

• Cooling Operation only.

Auto Restart Control

• Operation is restarted after power failure

at previous setting mode.

Anti-Freezing Control

• Anti-Freezing control for indoor heat

exchanger. (Cooling and Soft Dry)

Sleep Mode Auto Control

• The operation starts at SLo speed and

stops after 8 hours.

Indoor Fan Speed Control

• High, Medium and Low.

• Automatic Fan Speed Mode

– Heating : Fan speed varies from Me

→ SLo in accordance with

indoor heat exchanger.

– Cooling : Fan rotates at Hi and Me

speed. Deodorizing control is

available.

– Soft Dry : Fan rotates at SLo speed.

Deodorizing control is

available.

Airflow Direction Control

• Automatic air swing and manual adjusted

by remote control for vertical airflow.

• Manually adjusted by hand for horizontal

airflow.

Hot-Start Control

• The indoor fan stops until the indoor heat

exchanger temperature over 30°C.

• The indoor fan operates at SLo and Lo–

when indoor heat exchanger temperature

reaches 30°C ~ 41°C.

• Hot Start is completed when indoor heat

exchanger reaches 41°C.

Compressor Reverse Rotation

Protection Control

Outdoor Unit

Functions

• To protect compressor from reverse

rotation when there is a instantaneous

power failure.

Overload Protector

• CS-MA90KE and CS-MA120KE

2-stage OLP to protect the compressor.

Overload Protector will trip when

– Temperature of compressor increases to

120°C.

– High temperature or high current flow to

compressor.

(Refer circuit diagram for OLP characteristic)

• CS-MA70KE

OLP to protect the compressor.

– OLP characteristic can be referred to

circuit diagram.

Overload Protection Control

• Outdoor fan stops when indoor heat

exchanger temperature rises to 51°C and

restarts when the indoor heat exchanger

temperature drops to 49°C.

• Compressor stops when indoor heat

exchanger temperature reaches 65°C or

above.

(Heating Operation only)

Compressor Protection Control

• If the outdoor fan motor is not running after

compressor starts for 50 secs., compressor

will stop. (Cooling and Soft Dry Operation

only).

• When the unit is switched to “OFF” during

Heating Operation, 4-way valve stays at

Heating position for 5 minutes.

• Inner protector.

4-Way Valve Control

Outdoor Fan Operation Control

60 Secs. Forced Operation Control

• Once the compressor is activated, it does

not stop for 60 secs. (Stops immediate

with remote control stop signal.)

Deice Control

•

To prevent frosting at outdoor heat

exchanger. (Only for Heating Operation)

• Outdoor indoor heat exchanger is sensed

by TRS (Thermal Reed Switch).
